| 1 | Esophageal cancer: Risk factors,screening and endoscopic treatment in Western and Eastern countries显示文摘Esophageal cancer is one of the most unknown and deadliest cancers worldwide,mainly because of its extremely aggressive nature and poor survival rate.Esophageal cancer is the 6th leading cause of death from cancer and the 8th most common cancer in the world.The 5-year survival is around 15%-25%.There are clear differences between the risk factors of both histological types that affect their incidence and distribution worldwide.There are areas of high incidence of squamous cell carcinoma(some areas in China) that meet the requirements for cost-effectiveness of endoscopy for early diagnosis in the general population of those areas.In Europe and United States the predominant histologic subtype is adenocarcinoma.The role of early diagnosis of adenocarcinoma in Barrett's esophagus remains controversial.The differences in the therapeutic management of early esophageal carcinoma(high-grade dysplasia,T1 a,T1 b,N0) between different parts of the world may be explained by the number of cancers diagnosed at an early stage.In areas where the incidence is high(China and Japan among others) early diagnoses is more frequent and has led to the development of endoscopic techniques for definitive treatment that achieve very effective results with a minimum number of complications and preserving the functionality of the esophagus. | María José Domper Arnal ángel Ferrández Arenas ángel Lanas Arbeloa | 2015 | World Journal of Gastroenterology2015，21，26： | 116 |
| 2 | Endoscopic and surgical resection of T1a/T1b esophageal neoplasms: A systematic review显示文摘AIM: To investigate potential therapeutic recommendations for endoscopic and surgical resection of T1a/ T1b esophageal neoplasms. METHODS: A thorough search of electronic databases MEDLINE, Embase, Pubmed and Cochrane Library, from 1997 up to January 2011 was performed. An analysis was carried out, pooling the effects of outcomes of 4241 patients enrolled in 80 retrospective studies. For comparisons across studies, each reporting on only one endoscopic method, we used a random effects meta-regression of the log-odds of the outcome of treatment in each study. 'Neural networks' as a data mining technique was employed in order to establish a prediction model of lymph node status in superficial submucosal esophageal carcinoma. Another data mining technique, the 'feature selection and root cause analysis', was used to identify the most impor-tant predictors of local recurrence and metachronous cancer development in endoscopically resected patients, and lymph node positivity in squamous carcinoma (SCC) and adenocarcinoma (ADC) separately in surgically resected patients. RESULTS: Endoscopically resected patients: Low grade dysplasia was observed in 4% of patients, high grade dysplasia in 14.6%, carcinoma in situ in 19%, mucosal cancer in 54%, and submucosal cancer in 16% of patients. There were no significant differences between endoscopic mucosal resection and endoscopic submucosal dissection (ESD) for the following parameters: complications, patients submitted to surgery, positive margins, lymph node positivity, local recurrence and metachronous cancer. With regard to piecemeal resection, ESD performed better since the number of cases was significantly less [coefficient: -7.709438, 95%CI: (-11.03803, -4.380844), P < 0.001]; hence local recurrence rates were significantly lower [coefficient: -4.033528, 95%CI: (-6.151498, -1.915559),P < 0.01]. A higher rate of esophageal stenosis was observed following ESD [coefficient: 7.322266, 95%CI: (3.810146, 10.83439), P < 0.001]. A significantly greater number of SCC patients were submitted to surgery (log-odds, ADC: -2.1206 ± 0.6249 vs SCC: 4.1356 ± 0.4038, P < 0.05). The odds for re-classification of tumor stage after endoscopic resection were 53% and 39% for ADC and SCC, respectively. Local tumor recurrence was best predicted by grade 3 differentiation and piecemeal resection, metachronous cancer development by the carcinoma in situ component, and lymph node positivity by lymphovascular invasion. With regard to surgically resected patients: Significant differences in patients with positive lymph nodes were observed between ADC and SCC [coefficient: 1.889569, 95%CI: (0.3945146, 3.384624), P<0.01). In contrast, lymphovascular and microvascular invasion and grade 3 patients between histologic types were comparable, the respective rank order of the predictors of lymph node positivity was: Grade 3, lymphovascular invasion (L+), microvascular invasion (V+), submucosal (Sm) 3 invasion, Sm2 invasion and Sm1 invasion. Histologic type (ADC/SCC) was not included in the model. The best predictors for SCC lymph node positivity were Sm3 invasion and (V+). For ADC, the most important predictor was (L+). CONCLUSION: Local tumor recurrence is predicted by grade 3, metachronous cancer by the carcinoma insitu component, and lymph node positivity by L+. T1b cancer should be treated with surgical resection. | George Sgourakis Ines Gockel Hauke Lang | 2013 | World Journal of Gastroenterology2013，19，9： | 40 |
| 3 | Endoscopic submucosal dissection for superficial esophageal neoplasms显示文摘Endoscopic submucosal dissection(ESD) is currently accepted as the major treatment modality for superficial neoplasms in the gastrointestinal tract including the esophagus.An important advantage of ESD is its effectiveness in resecting lesions regardless of their size and severity of fibrosis.Based on excellent outcomes for esophageal neoplasms with a small likelihood of lymph node metastasis,the number of ESD candidates has increased.On the other hand,ESD still requires highly skilled endoscopists due to technical difficulties.To avoid unnecessary complications including perforation and postoperative stricture,the indications for ESD require careful consideration and a full understanding of this modality.This article,in the highlight topic series,provides detailed information on the indication,procedure,outcome,complications and their prevention in ESD of superficial esophageal neoplasms. | Satoshi Ono Mitsuhiro Fujishiro Kazuhiko Koike | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，5： | 32 |
| 4 | HIF-1α induces VE-cadherin expression and modulates vasculogenic mimicry in esophageal carcinoma cells显示文摘AIM:To investigate whether hypoxia inducible factor(HIF)-1αmodulates vasculogenic mimicry(VM)by upregulating VE-cadherin expression in esophageal squamous cell carcinoma(ESCC).METHODS:Esophageal squamous cancer cell lines Eca109 and TE13 were transfected with plasmids harboring small interfering RNAs targeting HIF-1αor VEcadherin.The proliferation and invasion of esophageal carcinoma cells were detected by MTT and Transwell migration assays.The formation of tubular networks of cells was analyzed by 3D culture in vitro.BALB/c nude mice were used to observe xenograft tumor formation.The relationship between the expression of HIF-1αand VE-cadherin,ephrin A2(Eph A2)and laminin5γ2(LN5γ2)was measured by Western blot and real-time polymerase chain reaction.RESULTS:Knockdown of HIF-1αinhibited cell proliferation(32.3%±6.1%for Eca109 cells and 38.6%±6.8%for TE13 cells,P<0.05).Both Eca109 and TE13cells formed typical tubular networks.The number of tubular networks markedly decreased when HIF-1αor VE-cadherin was knocked down.Expression of VEcadherin,Eph A2 and LN5γ2 was dramatically inhibited,but the expression of matrix metalloproteinase 2 had no obvious change in HIF-1α-silenced cells.Knockdown of VE-cadherin significantly decreased expression of both Eph A2 and LN5γ2(P<0.05),while HIF-1αexpression was unchanged.The time for xenograft tumor formation was 6±1.2 d for Eca109 cells and Eca109cells transfected with HIF-1αNeo control short hairpin RNA(sh RNA)vector,and 8.4±2.1 d for Eca109 cells transfected with an sh RNA against HIF-1α.Knockdown of HIF-1αinhibited vasculogenic mimicry(VM)and tumorigenicity in vivo.CONCLUSION:HIF-1αmay modulate VM in ESCC by regulating VE-cadherin expression,which affects VM formation through Eph A2 and LN5γ2. | Na-Na Tang Hong Zhu Hong-Jie Zhang Wei-Feng Zhang Hai-Lin Jin Lu Wang Pin Wang Gui-Jun He Bo Hao Rui-Hua Shi | 2014 | World Journal of Gastroenterology2014，20，47： | 25 |
| 5 | Evaluation of the 7^(th) edition of the TNM classification in patients with resected esophageal squamous cell carcinoma显示文摘AIM:To evaluate the prognostic factors and tumor stages of the 7th edition TNM classification for esophageal cancer.METHODS:In total,1033 patients with esophageal squamous cell carcinoma(ESCC)who underwent surgical resection with or without(neo)adjuvant therapy between January 2003 and June 2012 at the Thoracic Surgery DepartmentⅡof the Beijing Cancer Hospital,Beijing,China were included in this study.The following eligibility criteria were applied:(1)squamous cell carcinoma of the esophagus or gastroesophageal junction identified by histopathological examination;(2)treatment with esophagectomy plus lymphadenectomy with curative intent;and(3)complete pathologic reports and follow-up data.Patients who underwent non-curative(R1)resection and patients who died in hospital were excluded.Patients who received(neo)adjuvant therapy were also included in thisanalysis.All patients were restaged using the 7th edition of the Union for International Cancer Control and the American Joint Committee on Cancer TNM staging systems.Univariate and multivariate analyses were performed to identify the prognostic factors for survival.Survival curves were plotted using the Kaplan-Meier method,and the log-rank test was used to evaluate differences between the subgroups.RESULTS:Of the 1033 patients,273 patients received(neo)adjuvant therapy,and 760 patients were treated with surgery alone.The median follow-up time was 51.6mo(range:5-112 mo)and the overall 5-year survival rate was 36.4%.Gender,'p T'and'p N'descriptors,(neo)adjuvant therapy,and the 7th edition TNM stage grouping were independent prognostic factors in the univariate and multivariate analyses.However,neither histologic grade nor cancer location were independent prognostic factors in the univariate and multivariate analyses.The 5-year stage-based survival rates were as follows:ⅠA,84.9%;ⅠB,70.9%;ⅡA,56.2%;ⅡB,43.3%;ⅢA,37.9%;ⅢB,23.3%;ⅢC,12.9%andⅣ,3.4%.There were significant differences between each adjacent staging classification.Moreover,there were significant differences between each adjacent p N and p M subgroup.According to the p T descriptor,there were significant differences between each adjacent subgroup except between p T3 and p T4(P=0.405).However,there was no significant difference between each adjacent histologic grade subgroup and between each adjacent cancer location subgroup.CONCLUSION:The 7th edition is considered to be valid for patients with resected ESCC.However,the histologic grade and cancer location were not prognostic factors for ESCC. | Jia Wang Nan Wu Qing-Feng Zheng Shi Yan Chao Lv Shao-Lei Li Yue Yang | 2014 | World Journal of Gastroenterology2014，20，48： | 23 |
| 6 | Long noncoding RNA LINC00520 prevents the progression of cutaneous squamous cell carcinoma through the inactivation of the PI3K/Akt signaling pathway by downregulating EGFR显示文摘Background: Long noncoding RNAs (lncRNAs) play pivotal roles in various malignant tumors. Epidermal growth factor receptor (EGFR) signaling is associated with the pathogenesis of cutaneous squamous cell carcinoma (cSCC). This study aimed to explore the role of LINC00520 in the development of cSCC via EGFR and phosphoinositide 3-kinase-protein kinase B (PI3K/Akt) signaling pathways. Methods: A microarray analysis was applied to screen differentially expressed lncRNAs in cSCC samples. The A431 cSCC cell line was transfected and assigned different groups. The expression patterns of LINC00520, EGFR, and intermediates in the PI3K/Akt pathway were characterized using reverse transcription quantitative polymerase chain reaction (RT-qPCR) and Western blotting analysis. Cell proliferation, migration, and invasion were detected using the MTT assay, scratch test, and Transwell assay, respectively. Cell-based experiments and a tumorigenicity assay were conducted to assess the effect of LINC00520 on cSCC progression. This study was ended in September 2017. Comparisons between two groups were analyzed with t-test and comparisons among multiple groups were analyzed using one-way analysis of variance. The nonparametric Wilcoxon rank sum test was used to analyze skewed data. The enumerated data were analyzed using the chi-square test or Fisher exact test. Results: Data from chip GSE66359 revealed depletion of LINC00520 in cSCC. Cells transfected with LINC00520 vector and LINC00520 vector + si-EGFR showed elevated LINC00520 level but decreased levels of the EGFR, PI3K, AKT, VEGF, MMP-2 and MMP-9 mRNAs and proteins, and inhibition of the growth, migration and adhesion of cSCC cells, while the si-LINC00520 group showed opposite trends (all P < 0.05). Compared with the LINC00520 vector group, the LINC00520 vector + si-EGFR group showed decreased levels of the EGFR, PI3K, AKT, VEGF, MMP-2 and MMP-9 mRNAs and proteins, and inhibition of the growth, migration and adhesion of cSCC cells, while the LINC00520 vector+ EGFR vector group showed opposite results (all P < 0.05). Conclusion: Based on our results, LINC00520-targeted EGFR inhibition might result in the inactivation of the PI3K/Akt pathway, thus inhibiting cSCC development. | Xue-Ling Mei Shah Zhong | 2019 | Chinese Medical Journal2019，，4： | 20 |
| 7 | 食道的有鳞的房间癌 - 先锋损害和早诊断显示文摘 Squamous cell carcinoma of the esophagus (SCCE) carries a poor prognosis due to late diagnosis.Early detection is highly desirable,since surgical and endoscopic resection offers the only possible cure for esophageal cancer.Population screening should be undertaken in high risk areas,and in low or moderate risk areas for people with risk factors (alcoholics,smokers,mate drinkers,history of head and neck cancer,achalasia and lye stricture of the esophagus).Esophageal balloon cytology is an easy and inexpensive sampling technique,but the current methods are insufficient for primary screening due to sampling errors.Conventional endoscopy with biopsy remains the standard procedure for the identification of pre-malignant and early malignant changes in esophageal mucosa and endoscopic detection.It may be enhanced by several techniques such as dye and optic chromoendoscopy,magnifying endoscopy,and optical-based spectroscopic and imaging modalities.Since more than 80% of SCCE deaths occur in developing countries,where expensive techniques such as narrow band imaging (NBI) and autofluorescence imaging are unavailable,the most cost-effective tool for targeting biopsies may be Lugol dye chromoendoscopy,since it is easy,accurate,inexpensive and available worldwide.In ideal conditions,or in developed countries,is it reasonable to think that optimal detection will require a combination of techniques,such as the combination of Lugol’s chromoendoscopy and NBI to identify esophageal areas that require further characterization by a high resolution technique.The efficacy and cost-effectiveness will determine whether these modalities will become part of standard endoscopy practice. | Antonio Barros Lopes Renato Borges Fagundes | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，1： | 20 |
| 8 | Short term results of endoscopic submucosal dissection in superficial esophageal squamous cell neoplasms显示文摘AIM: To evaluate the efficacy of endoscopic submucosal dissection for superficial esophageal squamous cell neoplasms. METHODS: Between July 2007 and March 2009, 27 consecutive superficial esophageal squamous cell neoplasms in 25 enrolled patients were treated by endoscopic submucosal dissection. The therapeutic efficacy, complications, and follow-up results were assessed. RESULTS: The mean size of the lesions was 21 ± 13 mm (range 2-55 mm); the mean size of the resection specimens was 32 ± 12 mm (range 10-70 mm). The enblock resection rate was 100% (27/27), and en block resection with tumor-free lateral/basal margins was 88.9% (24/27). Perforation occurred in 1 patient who was managed by conservative medical treatments. None of the patients developed local recurrence or distant metastasis in the follow-up period. CONCLUSION: Endoscopic submucosal dissection is applicable to superficial esophageal squamous cell neoplasms with promising results. | Kouichi Nonaka Shin Arai Keiko Ishikawa Masamitsu Nakao Yousuke Nakai Osamu Togawa Koji Nagata Michio Shimizu Yutaka Sasaki Hiroto Kita | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，2： | 19 |
| 9 | Evaluation of preoperative staging for esophageal squamous cell carcinoma显示文摘Esophageal squamous cell carcinoma(ESCC) is known for its rapid progression and poor outcomes. China has the highest incidence and mortality in the world. Diagnoses made at early stages and accurate staging are associated with better outcomes, all of which can play a significant role in the selection of treatment protocols. ESCC is staged according to the widely accepted TNM system. Common imaging modalities used in staging ESCC before treatment include endoscopy, computed tomography(CT), positron emission tomography(PET) and magnetic resonance imaging(MRI). Endoscopic ultrasound is useful for staging tumor depth and nodal status. Narrow band imaging is valuable for early stage disease assessment. CT and PET provide additional valuable information regarding node and metastasis staging. The ability of MRI to delineate ESCC is continuously being improved and adds information regarding locoregional status to routine examinations. | Lin-Na Luo Long-Jun He Xiao-Yan Gao Xin-Xin Huang Hong-Bo Shan Guang-Yu Luo Yin Li Shi-Yong Lin Guo-Bao Wang Rong Zhang Guo-Liang Xu Jian-Jun Li | 2016 | World Journal of Gastroenterology2016，22，29： | 18 |
| 10 | Endoscopic submucosal tunnel dissection for largesuperficial esophageal squamous cell neoplasms显示文摘Endoscopic submucosal dissection(ESD)is a wellestablished treatment for superficial esophageal squamous cell neoplasms(SESCNs)with no risk of lymphatic metastasis.However,for large SESCNs,especially when exceeding two-thirds of the esophageal circumference,conventional ESD is time-consuming and has an increased risk of adverse events.Based on the submucosal tunnel conception,endoscopic submucosal tunnel dissection(ESTD)was first introduced by us to remove large SESCNs,with excellent results.Studies from different centers also reported favorable results.Compared with conventional ESD,ESTD has a more rapid dissection speed and R0 resection rate.Currently in China,ESTD for large SESCNs is an important part of the digestive endoscopic tunnel technique,as is peroral endoscopic myotomy for achalasia and submucosal tunnel endoscopic resection for submucosal tumors of the muscularis propria.However,not all patients with SESCNs are candidates for ESTD,and postoperative esophageal strictures should also be taken into consideration,especially for lesions with a circumference greater than three-quarters.In this article,we describe our experience,review the literature of ESTD,and provide detailed information on indications,standard procedures,outcomes,and complications of ESTD. | Ya-Qi Zhai Hui-Kai Li En-Qiang Linghu | 2016 | World Journal of Gastroenterology2016，22，1： | 17 |
| 11 | A phase Ⅱ study of paclitaxel and nedaplatin as front-line chemotherapy in Chinese patients with metastatic esophageal squamous cell carcinoma显示文摘AIM:To evaluate the efficacy and safety of paclitaxelnedaplatin combination as a front-line regimen in Chinese patients with metastatic esophageal squamous cell carcinoma(ESCC).METHODS:A two-center,open-label,single-arm phaseⅡstudy was designed.Thirty-nine patients were enrolled and included in the intention-to-treat analysis of efficacy and adverse events.Patients received 175mg/m2of paclitaxel over a 3 h infusion on 1 d,followed by nedaplatin 80 mg/m2in a 1 h infusion on 2 d every3 wk until the documented disease progression,unac-ceptable toxicity or patient’s refusal.RESULTS:Of the 36 patients assessable for efficacy,there were 2 patients(5.1%)with complete response and 16 patients(41.0%)with partial response,giving an overall response rate of 46.1%.The median progression-free survival and median overall survival for all patients were 7.1 mo(95%CI:4.6-9.7)and 12.4 mo(95%CI:9.5-15.3),respectively.Toxicities were moderate and manageable.Grade 3/4 toxicities included neutropenia(15.4%),nausea(10.3%),anemia(7.7%),thrombocytopenia(5.1%),vomiting(5.1%)and neutropenia fever(2.6%).CONCLUSION:The combination of paclitaxel and nedaplatin is active and well tolerated as a first-line therapy for patients with metastatic ESCC. | Yi-Fu He Chu-Shu Ji Bing Hu Ping-Sheng Fan Chang-Lu Hu Feng-Shou Jiang Jian Chen Lei Zhu Yi-Wei Yao Wei Wang | 2013 | World Journal of Gastroenterology2013，19，35： | 16 |
| 12 | Immunohistochemical prognostic markers of esophageal squamous cell carcinoma:a systematic review显示文摘Background: Esophageal squamous cell carcinoma(ESCC) is an aggressive malignancy, with a high incidence and poor prognosis. In the past several decades, hundreds of proteins have been reported to be associated with the prognosis of ESCC, but none has been widely accepted to guide clinical care. This study aimed to identify proteins with great potential for predicting prognosis of ESCC.Methods: We conducted a systematic review on immunohistochemical(IHC) prognostic markers of ESCC according to the 2009 Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA) Guidelines. Literature related to IHC prognostic markers of ESCC were searched from PubMed, Embase, Web of Science, and Cochrane Library until January 30 th, 2017. The risk of bias of these original studies was evaluated using the Quality in Prognosis Studies(QUIPS) tool.Results: We identified 11 emerging IHC markers with reproducible results, including eight markers [epidermal growth factor receptor(EGFR), Cyclin D1, vascular endothelial growth factor(VEGF), Survivin, Podoplanin, Fascin,phosphorylated mammalian target of rapamycin(p-mTOR), and pyruvate kinase M2(PKM2)] indicating unfavorable prognosis and 3 markers(P27, P16, and E-cadherin) indicating favorable prognosis of ESCC.Conclusion: Strong evidence supports that these 11 emerging IHC markers or their combinations may be useful in predicting prognosis and aiding personalized therapy decision-making for ESCC patients. | Chunni Wang Jingnan Wang Zhaoli Chen Yibo Gao Jie He | 2017 | Chinese Journal of Cancer2017，36，11： | 16 |
| 13 | Efficacy and safety of endoscopic submucosal tunnel dissection for superficial esophageal squamous cell carcinoma and precancerous lesions显示文摘AIM To evaluate the clinical outcomes of patients who underwent endoscopic submucosal tunnel dissection(ESTD) for esophageal squamous cell carcinoma(ESCC) and precancerous lesions.METHODS ESTD was performed in 289 patients. The clinical outcomes of the patients and pathological features of the lesions were retrospectively reviewed.RESULTS A total of 311 lesions were included in the analysis. The en bloc rate, complete resection rate, and curative resection rate were 99.04%, 81.28%, and 78.46%, respectively. The ESTD procedure time was 102.4 ± 35.1 min, the mean hospitalization time was 10.3 ± 2.8 d, and the average expenditure was 3766.5 ± 846.5 dollars. The intraoperative bleeding rate was 6.43%, the postoperative bleeding rate was 1.61%, the perforation rate was 1.93%, and the postoperative infection rate was 9.65%. Esophageal stricture and positive margin were severe adverse events, with an incidence rate of 14.79% and 15.76%, respectively. No tumor recurrence occurred during the follow-up period. CONCLUSION ESTD for ESCC and precancerous lesions is feasible and relatively safe, but for large mucosal lesions, the rate of esophageal stricture and positive margin is high. | Jin Wang Xiao-Nan Zhu Lin-Lin Zhu Wei Chen Yi-Han Ma Tao Gan Jin-Lin Yang | 2018 | World Journal of Gastroenterology2018，24，26： | 15 |
| 14 | Blood-based biomarkers for early detection of esophageal squamous cell carcinoma显示文摘Esophageal squamous cell carcinoma(ESCC)is a common malignant tumor of the digestive system worldwide,especially in China.Due to the lack of effective early detection methods,ESCC patients often present at an advanced stage at the time of diagnosis,which seriously affects the prognosis of patients.At present,early detection of ESCC mainly depends on invasive and expensive endoscopy and histopathological biopsy.Therefore,there is an unmet need for a noninvasive method to detect ESCC in the early stages.With the emergence of a large class of non-invasive diagnostic tools,serum tumor markers have attracted much attention because of their potential for detection of early tumors.Therefore,the identification of serum tumor markers for early detection of ESCC is undoubtedly one of the most effective ways to achieve early diagnosis and treatment of ESCC.This article reviews the recent advances in the discovery of blood-based ESCC biomarkers,and discusses the origins,clinical applications,and technical challenges of clinical validation of various types of biomarkers. | Ling-Yu Chu Yu-Hui Peng Xue-Fen Weng Jian-Jun Xie Yi-Wei Xu | 2020 | World Journal of Gastroenterology2020，26，15： | 14 |
| 15 | Micro RNA-1290 promotes esophageal squamous cell carcinoma cell proliferation and metastasis显示文摘AIM:To investigate the biological role of mi R-1290 in esophageal squamous cell carcinoma(ESCC) progression and invasion and the underlying mechanism.METHODS:Quantitative real-time polymerase chain reaction(q RT-PCR) was performed to evaluate mi R-1290 expression in ESCC tissue samples.The roles of mi R-1290 in cell proliferation,migration and invasion were identified using mi R-1290 mimic-transfected cells.In addition,the regulatory effect of mi R-1290 on suppressor of cancer cell invasion(SCAI) was evaluated using q RT-PCR,Western blot analysis and a dual luciferase reporter assay.RESULTS:mi R-1290 was significantly upregulated in ESCC tissue samples compared with normal adjacent tissues(9.213 ± 1.150 vs 1.000 ± 0.0),(P < 0.01).Upregulation of mi R-1290 was associated with tumor differentiation(P = 0.021),N classification(P = 0.006) and tumor-node-metastasis stage(P = 0.021) in ESCC patients.Moreover,ectopic mi R-1290 expression potently promoted ESCC cell growth(P < 0.01),migration(P < 0.01) and invasion(P < 0.01) in vitro.mi R-1290 overexpression in ESCC cell lines decreased SCAI expression at the translational level and reduced SCAI-driven luciferase-reporter activity(P < 0.01).CONCLUSION:Our findings suggested that mi R-1290 may play an oncogenic role in cellular processes of ESCC. | Ming Li Xiao-Yan He Zhi-Mei Zhang Shuo Li Li-Hua Ren Ri-Sheng Cao Ya-Dong Feng Yin-Lin Ji Ye Zhao Rui-Hua Shi | 2015 | World Journal of Gastroenterology2015，21，11： | 13 |
| 16 | A population-based survey of gastroesophageal reflux disease in a region with high prevalence of esophageal cancer in China显示文摘Background: The exact relationship between gastroesophageal reflux disease (GERD) and esophageal squamous cell cancer (ESCC) is far from clarification. The aim of this study was to investigate the epidemiology of GERD in a region with high prevalence of ESCC in China. Methods: A population-based, cross-sectional study was conducted in a high ESCC prevalent area, Anyang, Henan, China. All subjects fulfilled questionnaires and underwent gastroendoscopy with routine esophageal biopsy. The subjects were divided into GERD subtypes (reflux esophagitis [RE] and non-erosive reflux disease [NERD]) and controls. Odds ratios (ORs) and 95% confidence intervals (Cis) were calculated to examine risk factors for RE and NERD. Results: A total of 2844 subjects were finally enrolled. The prevalence of GERD (RE + NERD) was 17.3%. Among them, 271 (9.53%) adults were diagnosed with RE. The prevalence of RE increased with age (7.09% in 45-50 years, 8.00% in 51-60 years, and 9.53% in 61-69 years,x^2 = 62.216, P < 0.001). Sixty-seven (2.36%) subjects were diagnosed with the silent RE. A total of 221 (7.77%) subjects were diagnosed with NERD. Frequent liquid food consumption (OR [95% CI]: 1.502 [1.076-2.095]) was independent risk factor for RE as well as age, male gender, high body mass index (BMI), ever smoking. Age was independent risk factor for NERD. For silent RE, age, male gender, and frequent liquid food consumption were risk factors. Conclusions: In the population with high prevalence of ESCC, a high prevalence of GERD and inverted proportion of RE/NERD were presented. Age was an independent risk factor for GERD. The male gender, high BMI, smoking, and frequent liquid food consumption may be risk factors for RE but not for NERD. | Kun Wang Li Zhang Zhong-Hu He Zuo-Jing Liu Lu Zhang Nan Hu Zhu Jin Yang Ke Li-Ping Duan | 2019 | Chinese Medical Journal2019，，13： | 13 |
| 17 | Prognostic role of neutrophil-lymphocyte ratio in operable esophageal squamous cell carcinoma显示文摘AIM: To determine the prognostic significance of preoperative serum neutrophil-lymphocyte ratio(NLR) in esophageal squamous cell carcinoma(ESCC).METHODS: Data from 371 eligible patients with ESCC who had undergone surgery with curative intent at our institution between October 2000 and May 2007 were retrospectively recruited for analysis. The cutoff value of NLR was 3.0 as determined by the receiver operating characteristic curve, which discriminated between survival and death; the area under the curve was 0.709, and the sensitivity and specificity were 66.1% and 69.1%, respectively, at the cutoff point. The correlation between the NLR and clinicopathological characteristics was analyzed using a χ2 test. The prognostic influence of the NLR and other clinicopathological factors on cancer-specific survival(CSS) and recurrence-free survival(RFS) was studied using the Kaplan-Meier method. To evaluate the independent prognostic value of NLR, multivariate Cox regression models were applied.RESULTS:The median age of the patients was 57.0years,and 276/371(74.4%)patients were male.The NLR was≤3.0 in 80.1%(297/371)of the patients,and the remaining 19.9%(74/371)had an NLR>3.0.Median postoperative follow-up was 66.0 mo[interquartile range(IQR):49.0-76.0 mo],with a follow-up rate of 94%.Follow-up was not significantly different between patients with an NLR≤and>3.0(63.13±1.64 vs 61.52±3.66,P=0.711).However,higher preoperative serum NLR was associated with significantly increased risks of higher pathological tumor status(P=0.007).A significant,independent association between high preoperative serum NLR and poor clinical outcome was identified in a multivariate analysis for CSS(HR=1.591;P=0.007)and RFS(HR=1.525;P=0.013).Moreover,when patients were stratified by pathological tumor-node-metastasis(TNM)staging,the adverse effects of preoperative serum NLR on CSS(HR=2.294;P=0.008)and RFS(HR=2.273;P=0.008)were greatest in those patients with stageⅢA disease.CONCLUSION:Preoperative serum NLR is a useful prognostic marker to complement TNM staging for operable ESCC patients,particularly in patients with stageⅢA disease. | Hao Duan Xu Zhang Fei-Xiang Wang Mu-Yan Cai Guo-Wei Ma Hong Yang Jian-Hua Fu Zi-Hui Tan Yu-Qi Meng Xia-Yu Fu Qi-Long Ma Peng Lin | 2015 | World Journal of Gastroenterology2015，21，18： | 13 |
| 18 | Expression of Bmi-1 and PAI-1 in esophageal squamous cell carcinoma显示文摘AIM:To determine the correlation between invasiveness,migration and prognosis in esophageal squamous cell carcinoma(ESCC)and expression of the B-cellspecific Moloney leukemia virus insert site 1(Bmi-1)and plasminogen activator inhibitor-1(PAI-1).METHODS:Eighty previously untreated patients who underwent surgical excision of ESCC were included.The expression of Bmi-1 and PAI-1 was examined immunohistochemically in formalin-fixed paraffinembedded primary tissue specimens.The relationships between the expression of Bmi-1 and PAI-1,the clinicopathologic features of ESCC,and the survival rate of ESCC patients were also discussed.The correlation between Bmi-1 and PAI-1 protein expression in ESCC was analyzed.The relationship between Bmi-1 and PAI-1expression and ESCC prognosis was evaluated using a Cox regression model and Kaplan-Meier survival curve analysis.RESULTS:The rates of positive Bmi-1 and PAI-1 expression in ESCC were higher than those in normal esophageal tissue(P<0.05).The expression of Bmi-1and PAI-1 was correlated with depth of invasion and lymph node metastasis(P<0.05),but not with patient age,tumor size or nationality(P>0.05).The expression of Bmi-1 was positively correlated with that of PAI-1(P<0.05).The 10-year overall survival rate for all patients was 20%(16∕80).Univariate KaplanMeier survival analysis showed that patients with high expression of esophageal PAI-1 and Bmi-1 had lower survival,however,the difference was not statistically significant.Cox multivariate analysis showed that PAI-1and Bmi-1 were not independent factors for survival rate,while the depth of tumor invasion and metastasis were independent factors affecting patient survival.CONCLUSION:The expression of Bmi-1 and PAI-1plays a role in ESCC progression,and may be used as a prognostic marker in ESCC. | Yan Zhang Ya-Lou Zhang Hong-Ming Chen Hong-Wei Pu Wen-Jing Ma Xiao-Mei Li Hong Ma Xiao Chen | 2014 | World Journal of Gastroenterology2014，20，18： | 12 |
| 19 | Human papillomavirus DNA and P16~(INK4A) expression in concurrent esophageal and gastric cardia cancers显示文摘AIM:To investigate the relationship between human papillomavirus (HPV) infection and concurrent esophagus and gastric cardia cancer from the same patient (CC) and examine the significance of P16 INK4A protein expression.METHODS:Polymerase chain reaction was used to detect the presence of HPV type16 (HPV16).The expression of P16 INK4A protein was detected using immunohistochemistry.RESULTS:Among the CC specimens,HPV16-DNA was found in eight cases of esophageal squamous cell carcinoma (ESCC) and five cases of gastric cardia adenocarcinoma (GCA),respectively (47% vs 29%),and two of both ESCC and GCA.P16 INK4A was highly expressed in both ESCC and GCA.In the HPV-associated positive CC,higher P16 INK4A expression was observed in the GCA than in the ESCC (75% vs 25%,P < 0.05).CONCLUSION:HPV16 as a correlated risk factor may play an important role in the development of ESCC and GCA.P16 INK4A may be a screening index in the HPVassociated carcinoma of gastric cardia. | Guang-Cheng Ding,Tao Guo,Department of Gastroenterology,The First Affiliated Hospital and The Fifth Affiliated Hospital,Zhengzhou University,Zhengzhou 450052,Henan Province,China Jing-Li Ren,Xin Song,Sheng-Li Zhou,Zong-Min Fan,LiDong Wang,Henan Key Laboratory for Esophageal Cancer Research,Department of Gastroenterology,The First Affiliated Hospital,College of Basic Medicine,Zhengzhou University,Zhengzhou 450052,Henan Province,China Fu-Bao Chang,Department of Thoracic Surgery,Linzhou Center Hospital,Linzhou 456500,Henan Province,China Ji-Lin Li,Department of Pathology,Yaocun Esophageal Cancer Hospital,Linzhou 456500,Henan Province,China Ling Yuan,Department of Oncoradiotherapy,Henan Province Tumor Hospital,Zhengzhou 450003,Henan Province,China Yi Zeng,Institute of Virology,Chinese Academy of Preventive Medicine,Beijing 100052,China | 2010 | World Journal of Gastroenterology2010，16，46： | 11 |
| 20 | Monitoring disease progression and treatment efficacy with circulating tumor cells in esophageal squamous cell carcinoma: A case report显示文摘This study investigated whether changes in circulating tumor cell(CTC) numbers reflect tumor progression and treatment efficacy in esophageal squamous cell carcinoma(ESCC). A 47-year-old male patient with ESCC is presented in this case study. The patient was evaluated for a series of serum tumor markers and subjected to radiological examinations before and after surgery and during follow-up over the course of five years. In addition, the CTCs in 7.5 m L of peripheral blood were enriched by magneticactivated cell sorting negative selection and identified by immunofluorescence staining. Serum tumor markers remained within normal ranges and were discordant with imaging scans during the follow-up. Initially, one CTC was detected in the peripheral blood sample, and 14 were observed seven days after the operation. After 12 wk, subcutaneous metastases and bone metastases occurred, and the number of CTCs increased to 84. After 48 wk, lung metastases were noted, and the CTC level was 21. At 104 wk, the number of CTCs was 14, and disease recurrence was detected by positron emission tomography-computed tomography. The CTC counts were in accord with the imaging studies at several time points. The additional information provided by CTC enumeration could thus facilitate monitoring of disease status and treatment efficacy and provide support for treatment decisions. | Yuan-Yuan Qiao Kai-Xuan Lin Ze Zhang Da-Jin Zhang Cheng-He Shi Ming Xiong Xiu-Hua Qu Xiao-Hang Zhao | 2015 | World Journal of Gastroenterology2015，21，25： | 11 |
